High temperatures can have several negative effects on corals:
1. Increased susceptibility to disease: High temperatures can weaken the immune system of corals, making them more susceptible to various diseases. This can lead to higher rates of coral mortality.
2. Coral bleaching: Corals have a symbiotic relationship with a type of algae called zooxanthellae, which provide them with essential nutrients through photosynthesis. Under high temperatures, corals expel these zooxanthellae, causing them to appear pale or "bleached". This can disrupt the coral's nutrient supply and lead to eventual death if the stress persists.
3. Coral erosion: High temperatures can also cause corals to undergo physical stress, leading to a breakdown of their structure, known as coral erosion. This can result in the loss of coral reefs, which are crucial habitats for a variety of marine organisms.
It's important to note that while increased coloration is often associated with healthy corals, high temperatures causing corals to become more colorful is not a typical response. Instead, it is an indication of stress and potential damage to the coral reef ecosystem.
